CentOS 6.5 LAMP环境搭建及监控方案

一、搭建LAMP环境

1. 安装Apache

前置准备：

yum install -y gcc gcc-c++ gcc-devel cmake

安装apr：

tar xvf apr-1.5.0.tar.gzcd apr-1.5.0./configure --prefix=/usr/local/aprmake && make install

安装apr-util：

tar xvf apr-util-1.5.3.tar.gzcd apr-util-1.5.3./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/aprmake && make install

安装pcre：

tar xvf pcre-8.33.tar.gzcd pcre-8.33./configure --prefix=/usr/local/pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-utilmake && make install

安装Apache：

tar xvf httpd-2.4.7.tar.gzcd httpd-2.4.7./configure --prefix=/usr/local/httpd --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre --enable-so --enable-rewritemake && make install

启动Apache：

cd /usr/local/httpd/bin/./apachectl start

验证Apache：

netstat -antl | grep 80

2. 安装MySQL

解压并编译安装：

tar xf mysql-5.6.10.tar.gzcd mysql-5.6.10cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr/local/mysql -DMYSQL_DATADIR:PATH=/database -DWITH_DEBUG:BOOL=on -DWITH_EXTRA_CHARSETS:STRING=all -DWITH_INNOBASE_STORAGE_ENGINE:BOOL=on -DWITH_PARTITION_STORAGE_ENGINE:BOOL=onmake && make install

解决常见错误：

yum install -y ncurses-develrm CMakeCache.txtmake && make install

新建MySQL用户及目录：

mkdir /databasemkdir /usr/local/mysql/var/log -pmkdir /usr/local/mysql/var/run -pmkdir /usr/local/mysql/etcmkdir /usr/local/mysql/binloguseradd mysqlchown -R mysql:mysql /database /usr/local/mysql/

修改MySQL配置文件：

cp support-files/my-default.cnf /usr/local/mysql/etc/my.cnfvim /usr/local/mysql/etc/my.cnf

初始化数据库：

/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/database --user=mysql

添加MySQL自启动：

cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql5.6dchkconfig --add mysql5.6dchkconfig mysql5.6d onservice mysql5.6d start

设置root密码：

/usr/local/mysql/bin/mysql -urootmysql> update user set password='123654' where user='root';

3. 安装PHP

4. 安装Nagios和NRPE

在监控主机上安装Nagios：

tar xvf nagios-3.4.3.tar.gzcd nagios./configure --prefix=/usr/local/nagios --with-gd-lib=/usr/local/gd/lib --with-gd-inc=/usr/local/gd/includemake all && make installmake install-initmake install-commandmodemake install-config

5. 配置Apache和Nagios

Apache配置：

vim /usr/local/httpd/conf/httpd.conf

添加Nagios CGI路径：

# settings for nagiosScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
   
        AuthType Basic    Options ExecCGI    AllowOverride None    Order allow,deny    Allow from all    AuthName "Nagios Access"    AuthUserFile /usr/local/nagios/etc/htpasswd    Require valid-user
   Alias /nagios /usr/local/nagios/share
   
        AuthType Basic    Options None    AllowOverride None    Order allow,deny    Allow from all    AuthName "nagios Access"    AuthUserFile /usr/local/nagios/etc/htpasswd    Require valid-user

创建admin用户并设置密码：

/usr/local/httpd/bin/htpasswd -c /usr/local/nagios/etc/htpasswd admin

6. 被监控机安装Nagios插件和NRPE

在被监控机上安装Nagios插件：

tar xvf nagios-plugins-1.4.16.gzcd nagios-plugins-1.4.16./configure --prefix=/usr/local/nagios/make && make install

安装NRPE：

tar xf nrpe-2.14.tar.gzcd nrpe-2.14./configuremake all && make install-pluginmake install-daemonmake install-daemon-config

配置NRPE：

添加监控主机：

com2sec notConfigUser 192.168.1.124 publicview all .1 80access notConfigGroup "" any noauth exact all none none

重启SNMP服务：

service snmpd restart

8. 配置Nagios

创建自定义配置文件：

cd /usr/local/nagios/etc/objects/vim hosts.cfg

定义主机：

define host {    use linux-server    host_name linux-43    alias test    address 192.168.1.43}

创建主机组：

vim hostgroups.cfgdefine hostgroup {    hostgroup_name zj-servers    alias zj-servers    members linux-43}

创建服务：

vim services.cfgdefine service {    use local-service    host_name linux-43    service_description check-host-alive    check_command check-host-alive}

修改Nagios主配置文件：

vim /usr/local/nagios/etc/nagios.cfg

添加配置文件路径：

cfg_file=/usr/local/nagios/etc/objects/hosts.cfgcfg_file=/usr/local/nagios/etc/objects/hostgroups.cfgcfg_file=/usr/local/nagios/etc/objects/services.cfg

9. 安装Cacti

安装依赖软件：

yum install rrdtool* -y

创建数据库：

mysql -uroot -p123654create database cacti;grant all privileges on cacti.* to "cactier"@"localhost' identified by '123654';flush privileges;

安装Cacti：

tar xvf cacti-0.8.8b.tar.gzcd cacti-0.8.8bmv cacti-0.8.8b /usr/local/httpd/htdocs/cacticd /usr/local/httpd/htdocs/cacti/mysql -ucactier -p123654 cacti < cacti.sql

修改Cacti配置文件：

编译安装：

./configure --prefix=/usr/local/ntopmake && make install

设置ntop密码：

/usr/local/ntop/bin/top -u ntop -c -d

添加开机自启动：

echo "/usr/local/ntop/bin/top -u ntop -c -d" >> /etc/rc.local

11. 安装Cacti插件

安装设置插件：

tar xf settings-v0.7-1.tgz -C /usr/local/httpd/htdocs/cacti/pluginsvim /usr/local/httpd/htdocs/cacti/include/config.php$plugins[] = "settings";

激活插件：

Console > Settings > settings

安装monitor插件：

tar xf monitor-v1.3-1.tgz -C /usr/local/httpd/htdocs/cacti/pluginsvim /usr/local/httpd/htdocs/cacti/include/config.php$plugins[] = "monitor";

安装thold插件：

tar xf thold-v0.5.0.tgz -C /usr/local/httpd/htdocs/cacti/pluginsvim /usr/local/httpd/htdocs/cacti/include/config.php$plugins[] = "thold";

完成

通过以上步骤，您已经成功搭建了一个基于 CentOS 6.5 的LAMP环境，并完成了Nagios、Cacti、ntop等监控工具的安装与配置。系统已实现对多台服务器的全面监控，并通过邮件报警等方式实现了自动化监控。
